Intangiriro

Ethyl trans-butenoate nikintu kama. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano yikigo:

Ubwiza:

Ethyl trans-butenoate ni amazi atagira ibara afite impumuro idasanzwe. Nibyoroshye cyane kuruta amazi afite ubucucike bwa 0,9 g / mL. Gukemuka mumashanyarazi atandukanye, nka Ethanol, ethers na naphtène, mubushyuhe bwicyumba.

Koresha:

Ethyl trans-butenate ifite uburyo butandukanye mubikorwa byinganda. Ikoreshwa cyane ni nkigihe cyo guhuza intungamubiri kugirango hategurwe ibindi bintu kama, nka oxalates, ester solvents na polymers. Irashobora kandi gukoreshwa nk'imyenda, ibishishwa bya reberi, hamwe n'umuti.

Uburyo:

Uburyo bwo gutegura trans-butenoate Ethyl ester mubusanzwe tubonwa nigisubizo cya acide trans-butenoic hamwe na Ethanol. Iki gicuruzwa kiboneka mugushyushya aside trans-butenic na Ethanol mugihe cya acide kugirango ikore ester.

Amakuru yumutekano:

Ethyl trans-butenoate irakaza amaso nuruhu kandi irashobora gutera uburibwe bwamaso nuruhu. Guhumeka umwuka wacyo bigomba kwirindwa mugihe ukoresha uruganda, kandi ibikorwa bigomba gukorerwa ahantu hafite umwuka mwiza. Iyo ubitse, bigomba gushyirwa mubintu byumuyaga mwinshi, kure yumuriro na okiside.

Mbere: Dihydrocarvyl acetate (CAS # 20777-49-5)

Ibikurikira: trans-2-Hexenyl acetate (CAS # 2497-18-9)
